Type: MCQ-numerical-Medium-Class 11
3O₂(g) ⇌ 2O₃(g) for the above reaction at 298 K, Kc is found to be 3.0 × 10⁻⁵⁹. If the concentration of O₂ at equilibrium is 0.040 M then concentration of O₃ in M is
A
2.4 × 10³¹
B
1.2 × 10²¹
C
4.38 × 10⁻³²
D
1.9 × 10⁻⁶³
Correct Answer
Option C
Detailed Explanation
Using the equilibrium expression Kc = [O₃]²/[O₂]³, and substituting the given values, the concentration of O₃ is calculated to be 4.38 × 10⁻³² M.
